Abstract
Optical fiber closure including a pair of mating surfaces one of which is provided with a groove having a first volume and a deformable sealing member mounted in and extending outwardly from the groove with the groove having a volume larger than the volume of the sealing member; upon the mating surfaces being forced together, the sealing member is compressed and deforms within the groove and provides a substantially fluid-tight seal between the surfaces. The closure may include a plurality of cable clamps provided with outwardly extending deformable sealing members which are received in grooves having a larger volume than the volume of the sealing members whereby upon the cable clamps being forced into engagement with optical fiber cables entering or exiting the closure the sealing members are received in the grooves and compressed and deformed within the grooves to provide a fluid-tight seal between the cable clamps and optical fiber cables entering or exiting the closure. Closure apparatus also may include a plurality of individual cable clamps each provided with individual sealing means and with each cable clamp being capable of being disengaged from a fiber optical cable withou…
